Correct option:
Required
Explanation:
After authentication, it is generally required to generate a new session for the user. This ensures that the user has a unique session to track their interactions with the application and maintain a secure environment. If the application is deployed across multiple servers (e.g., in a load-balanced environment), managing sessions properly becomes even more critical to ensure consistency and security. Without a new session, it could lead to security risks like session hijacking or session fixation.
